There are various pre-set times that can be easily adjusted to suit your heating & domestic hot water requirements. For ease of installation a Wireless Room Thermostat is supplied which can be located anywhere within the property. The unit has In-built Weather Compensation which will automatically modulate and reduce the Boilers input temperature in relation to the external temperature which reduces Boiler cycling and could save up to 15% energy usage. A further energy saving measure would be to add our optional Titanium PV Immersion heater to the Cylinder which when connected to a Solar PV diverter will automatically start heating the cylinder within the unit. 8 Domestic Hot Water Expansion Vessel High Temperature Thermal cut-out Tundish Control Panel Pressure Sensor Connection for Backup Immersion Heater or Solar PV Heater Central Heating Expansion Vessel Zone Valves Automatic Air Vent Stainless Steel Heat Exchanger Magnetic Filter ErP Smart Pump 140 litre Stainless Steel Cylinder Drain Valves Domestic Hot Water Cold Mains Inlet Tundish Central Heating Return Central Heating Flow Top Entry Plumbing Connections9 Comet Combination Unit Technical Information 9kW12kW14.4kW Electrical supply 240V - 50Hz Load currentAmp38 5060 Minimum permitted Cable diametermm²10 1616 Circuit protectionAmp50 6380 Primary system pressure relief valve settingBar3.0 Primary system operating pressure (min)Bar1.0 Thermal cut-out°C100 Expansion vesselCapacity 12L - pre-charged 1.5 Bar Outlet flow temperature°C30 to 85 Primary circulating pumpGrundfos UPM3 or Wilo-Para 15/7 iPWM Safety valveBarOpening pressure: 3 Bar Hydraulic connections22mm 17° to 55° Hot Water Recovery Time44mins36mins29mins 17° to 65° Hot Water Recovery Time72mins56mins45mins Heating outputBTU307094094549134 Space heating ERPD Maximum water supply pressureBar10 Cylinder operating pressure (secondary)Bar3 Cylinder operating pressure (primary max)Bar2.5 Cylinder operating pressure (secondary max)Bar5.5 Expansion relief valve setting (secondary)Bar6 Thermostat°C30 to 70 Tank capacityltr140 Temperature-pressure valve95°C/6Bar TP 152 - 1/2 Expansion vessel12ltr3 Bar (charge pressure) Hydraulic connectionsCopper pipe ø 22 x 1 Optional immersion heater3000w240volt Net Weightkg106.8 Gross Weightkg246 Dimensionsmm1745(h) x 580(w) x 630(d) Cylinder ERPC CYLINDER DETAILS OPTIONAL EXTRAS EHC Shower Flow Sensor Back-up Immersion Heater Solar PV Immersion Heater33 M0235 - Magnetic Filter ESFS15C - Shower Flow Sensor EC10007 - Pump Value EC10005 - Auto Air Vent EC10006 - Grundfox UPM3 or Wilo Pump EC10011 - Twin Channel Heatpack 22mm Compression lockshield Valve Supplied with Pump Washer In-line Filter with Strainer and Magnetic stack 3/4” BSP connections High Efficiency ErP Compliant.
